Dear iboat experts, I was recently given an older 17' Penn Yann (1977?) with a mercruiser i/o engine (straight six) that needs to have some work done on the lower unit. The older gentlemen also included a replacement out drive (upper and low) just needing to be installed. My question is what difference does it make what out drive is put in as long as its an Alphe 1 or older? I see 1.5 and 1.8 ratio out drives and I've also seen out drives marked 120 / 165 / MR. they look the same to me.
